Used as a neutron absorber in nuclear reactors, particularly in control rods and emergency shutdown systems, due to its high neutron capture cross-section. Employed in boron neutron capture therapy (BNCT) for treating certain cancers, where it delivers boron-10 to tumor cells for targeted irradiation. Also utilized in radiation shielding materials and as a tracer in neutron detection instruments. Its stable isotope properties make it valuable in nuclear research and diagnostics.
